Objective To compare medical students' learning curve between Macintosh laryngoscope and optical laryngoscope in endotracheal intubation and to decide which one is more suitable for novice personnel.Methods Totally 26 interns after being trained by experienced anesthesiologists were enrolled in this study.They performed intubation on 6 patients by using both Macintosh laryngoscope and optical laryngoscope ( each laryngoscope for 3 patients) under the supervision of experienced anesthesiologists.The sequence of laryngoscope was determined by computer-generated random number list.Results Totally 149 patients who were ready to receive surgery under general anesthesia were enrolled in this randomized crossover controlled study.Duration of intubation was significantly shorter in Airtraq group (78 -± 33 ) s than in Macintosh group (114 ± 32) s,P ＜ 0.001.Intubation success rate was significantly higher in Airtraq group than in Macintosh group ( 87.8％ vs.66.7％,P ＜ 0.05 ).Conclusions With the advantages of rapid learning curve,higher intubation success rate and shorter intubation duration,Airtraq laryngoscope is easier to master for novice personnel.

Objective To investigated the efficacy of celecoxib for postoperative analgesia after endoscopic nasal surgery. Methods One hundred and twenty ASA Ⅰ or Ⅱ patients of both sexes aged 18-64 yr were randomly assigned to one of three groups ( n = 40 each): control group ( group C); celecoxib 200 group ( group CEL1 ) and celecoxib 400 group ( group CEL2 ). The patients took celecoxib 200 and 400 mg by mouth at 1 h before induction of anesthesia in group CEL1 and CEL2 respectively. Anesthesia was induced with midazolam,propofol, remifentanil and rocuronium and maintained with iv propofol and remifentanil infusion. VAS was used to assess postoperative pain (0 = no pain, 10 = worst pain). In PACU when VAS score ≥3, the patients were given fentany125 μg iv every 5-10 min until the VAS score ＜ 3. After being discharged from PACU, the patients received celecoxib 200 mg every 12 h for 5 days in the 2 celecoxib groups. Oxycodone 5 mg was used as rescue analgesic when VAS score ≥ 4 until the VAS score ＜ 4. The number of patients who needed fentanyl for analgesia in PACU, the number of patients who needed oxycodone within 6 h, 6-24 h and day 2-5 after operation and side effects after operation were recorded. Analgesic efficacy was assessed at day 5 after operation and the satisfactory rate of patients calculated. Blood samples were obtained at 0, 6 and 48 h after operation for determination of PGE2,6-k-PGF1α and TXB2 concentrations. TXB2/6-k-PGF1α was calculated. Results The number of patients who needed fentanyl in PACU and the number of patients who needed oxycodone within 6 h and 6-24 h after operation were less, the satisfactory rate was significantly higher, and PGE2 concentrations in blood were significantly lower at 48 h after operation in the 2 celecoxib groups than in group C ( P ＜ 0.05 or 0.01 ). There was no significant difference in each index between the 2 celecoxib groups ( P ＞ 0.05 ). There was no significant difference in TXB2/6-k-PGF1α at each time point among the three groups. Nausea and vomiting occurred in one patient after operation in group C, but side effects were not observed in the 2 celecoxib groups. Conclusion Celecoxib given before and after operation can effectively relieve postoperative pain after endoscopic nasal operation by reducing PGE2 concentrations in blood.

Objective To study the effectiveness of microwave ablation in treating HCC.Methods A total of 98 nodules in 56 cases of HCC were treated via appropriate puncture approach ac-cording to the volume, amount and site of tumor nodules. Results Only 1 patient failed to finish treatment since he could not suffer the pain. The other 55 patients finished without a hitch. Clinical and imaging findings were analyzed for change of physiology. Conclusion The microwave ablation is effective for the treatment of HCC. Such therapy can be important supplement of direct surgical man-agement. Its effect mainly depends on accurate puncture approach and enough diametric range. Mean-while, reasonable puncturing method should be selected.

After operations such as organ transplantation or cardiopulmonary bypass complicated with is-chemia/reperfusion injury,activated inflammatory cells can express and secret HMGB1,and cooperate with other inflammation factor to induce tissue damage.The mechanism is HMGB1 actives such receptors as TLRs,RAGE,TM,and NF-κB transcription factor,P38MAPK pathway,induce releasing of HMGB1 itself and other inflammation factors.Different with sepsis,HMGB1 emerges much earlier,lasting longer.Inter-ference therapy of HMGB1 could effectively decrease secretion of HMGB1 after ischemia/reperfusion injury.

Objective To evaluate the clinic efficacy of sufentanil and remifentanil by target- controlled infusion (TCI) combined with propofol in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).Methods Sixty patients,ASA Ⅰ ～ Ⅱ,undergoing elective EBUS-TBNA were randomly divided into group S ( sufentanil group),group R (remifentanil group) and group SR (sufentanil + remifentanil group),each group were twenty patients.The anesthesia of all groups is propofol intravenous anesthesia with 2％ lidocaine topical anesthesia,to controll BIS between 50 and 60 during surgery.Heart rate(HR),mean arterial pressure(MAP) pulse oxygen saturation( SpO2 ) and respiratory rate (RR) were recorded and compared 5mins after entering room(T0),30mins after the beginning of surgery(T1 ) and after surgery(T3).Arterial blood gas and the times of cough during surgery were also recorded and compared in all groups.The use of propofol and lidocaine,the wake-up time,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were also obtained.Results ( 1 ) RR decreased distinctly in group R and PaCO2 increased distinctly in group S and group R compared with that of group SR (P ＜0.05) during surgery.(2)The times of cough and the wake-up time lessened distinctly in group R and group SR compared with that of group S ( P ＜0.05 ).(3) The use of propofol and lidocaine,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were similar in all groups ( P ＞ 0.05 ).Conclusion Sufentanil compounded remifentanil by TCI combined with propofol is a safe and feasible anesthesia option for EBUS-TBNA,which provides better efficacy,high satisfaction and less side effects compared with using alone of sufentanil and remifentanil respectively.

Objective To investigate the relationship between cognitive function and emotional status in functional constipation patients.Methods Thirty-five functional constipation patients (the functional constipation group) and 24 healthy controls (the HCs) were enrolled in an event-related potential (ERP),behavior and electroeneephalogram study while performing an oddball auditory task.Response time,accuracy,latency and P300 amplitude were compared between the two groups.The Hamilton depression rating scale (HAMD-17),Hamilton anxiety scale (HAMA),symptom check list-90 (SCL-90) and Eysenck personality questionnaire (EPQ) were administered prior to the oddball task.Results The average HAMD-17,HAM A and SCL-90 (the somatization,obsessive-compulsive disorder,depression,anxiety and psychosis dimensions) scores of the functional constipation group differed significantly from those of the HCs.The intro-extraversion and neurosis dimensions of the EPQ were also significantly different.There was no significant difference in response time or latency between the two groups.The ERP results showed that the P300 amplitudes at the F3 and F7 sites were significantly different between the functional constipation group and the HCs.But there was no significant difference in P300 latencies at F3 or F7 between the two groups.Conclusions The findings suggest that patients with functional constipation are more susceptible to depression and anxiety,as well as somatization,obsessive-compulsive tendencies and other neurotic personality characteristics.Patients may employ psychological defense mechanisms to avoid the depression and anxiety.The ERP results imply there may be the implicit cognitive dysfunction with emotion in patients with functional constipation.

Objective To evaluate the safety and efficacy of hepatectomy in combination with portal azygous disconnection for primary hepatocellular carcinoma (HCC) complicated with severe portal hypertension (PHT). Methods Clinical data of 30 cases of HCC complicated with PHT treated in our hospital from April 2005 to April 2008 were retrospectively analyzed. All 30 cases were randomly divided into the single operation group (group Ⅰ ) and combined group (group Ⅱ ). Results After operation, there were no significant statistical differences in rates of complications such as hepatic encephalopathy, ascites, stress ulcer, etc. and recovery of liver function between the 2 groups. The WBC and PLT counts in the blood samples of group Ⅱ were higher than those in group Ⅰ after operation. The postoperative 1- and 2-year hemorrhagic rates were lower in group Ⅱ than in group Ⅰ .Conclusion Hepatectomy in combination with portal azygous disconnection is safe and feasible for treatment of HCC complicated with PHT.

OBJECTIVE:To study the protective effects of total flavone from Prunus cerasifera fruits(PCE)on alcoholic liver disease(ALD)in rats,and provide experimental basis for developing new medicines for anti-ALD. METHODS:40 rats were ran-domly divided into normal group(distilled water),model group(distilled water),silibinin group [positive control,30 mg/(kg·d)] and PCE high-dose,low-dose groups [80,40 mg/(kg·d)],8 in each group. All rats were intragastrically administrated(10 mL/kg) every morning,once,for 6 weeks;meanwhile,except for normal group,rats in other groups received 50% alcohol(10 mL/kg) once intragastrically every afternoon to induce ALD model. After administration,heart,liver,spleen and other organ indexes,sub-cutaneous fat,brown fat,abdominal fat indexes were determined,as well as serum biochemical indexes [glutamate transaminase (ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),direct bilirubin(DBIL),indirect bilirubin(IBIL),gamma-glu-tamyl transpeptidase(GGT),and total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL),low-density lipopro-tein (LDL)] level and liver biochemical indexes [superoxide dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),TC,TG] and TC,TG levels in feces;pathological changes of liver and kidney tissues were observed. RESULTS:Compared with normal group,heart,liver,spleen indexes,subcutaneous fat,abdominal fat indexes in model group were in-creased(P<0.05 or P<0.01),brain index and brown fat index were decreased(P<0.05);HDL level and HDL/TC ratio in serum were decreased,other serum indexes were increased(P<0.05 or P<0.01);SOD,GSH-Px levels in liver tissue were decreased, other above-mentioned liver biochemical indexes were increased(P<0.01);TC,TG levels in feces were increased(P<0.01);liv-er and kidney showed obvious lesions. Compared with model group,the above-mentioned indexes in silibinin group and PCE high-dose group were significantly improved (P<0.05 or P<0.01);ALT,AST in serum and MDA level in liver tissue in PCE low-dose group were significantly decreased(P<0.01),and SOD,GSH-Px levels in liver tissue were significantly increased(P<0.05);lesion degree of liver and kidney and lipid accumulation in liver were reduced in administration groups. CONCLUSIONS:PCE may play a role in anti-ALD by anti-oxidation,promoting liver cell regeneration and regulating lipid metabolism.
